Definitions

  • the present invention relates to a conveyor for the transport of bulk materials and contains three pairs of supporting cables, which are respectively located approximately vertically one above the other.
  • the conveyor further contains a self-contained conveyor belt, which is movable along the supporting cables from a loading station to an unloading station and in the end stations is guided over return drums.
  • supporting beams which are located at a distance apart and are aligned transversely to the longitudinal extent of the conveyor belt and at the ends of which are mounted rollers, which roll along the middle and the lower supporting cables.
  • the conveyor further contains supporting frames, which are located at a distance apart in the longitudinal direction of the conveyor and by which the supporting cables are mutually connected.
  • the supporting frames are formed by at least two at least approximately vertically aligned supporting struts and at least two at least approximately horizontally aligned connecting struts and, furthermore, the upper ends of the supporting struts are connected to respectively one of the two upper supporting cables.
  • the connecting struts are connected by clamping devices to the middle and the lower supporting cables.
  • Conveyors of this type which are known, for example, from European patents EP 1295817 B1 (corresponding to U.S. Pat. No. 6,588,583) and EP 1452466 B1 (corresponding to U.S. Pat. No. 6,935,490), serve to convey bulk materials, such as overburden materials, ores, coal and the like, from a loading station to an unloading station.
  • These conveyors have supporting cables, along which a self-contained conveyor belt is movable. Fastened for this purpose to the top side of the conveyor belt are transversely aligned supporting beams, at both ends of which are mounted rollers by which the conveyor belt is moved along two pairs of supporting cables disposed vertically one above the other.
  • the rollers are configured on both sides with roller flanges.
  • the conveyor belt is guided over return drums.
  • a further pair of supporting cables is provided above the two pairs of supporting cables.
  • mutually spaced supporting frames which serve to connect the supporting cables one to another to form a stable unit. That strand of the conveyor belt which is moved along the middle supporting cables serves to convey bulk materials from a loading station to an unloading station.
  • the lower strand of the conveyor belt is moved back along the two lower supporting cables from the unloading station to the loading station.
  • the upper supporting cables serve to stabilize the conveyor.
  • the supporting frames are formed by two vertically aligned supporting struts and by two horizontally aligned connecting struts, which latter connect the supporting struts one to another.
  • the upper ends of the vertically aligned supporting struts are fixedly connected to the two upper supporting cables, and the two horizontally aligned connecting struts are fixedly connected by vertical webs to the middle supporting cables and to the lower supporting cables.
  • a conveyor for transporting bulk materials.
  • the conveyor contains three pairs of supporting cables disposed vertically one above another and include lower supporting cables, middle supporting cables and upper supporting cables.
  • the conveyor further has return drums and a self-contained conveyor belt being movable along the supporting cables and at ends of the conveyor.
  • the conveyor belt is guided over the return drums.
  • Supporting beams are fastened to the conveyor belt.
  • the supporting beams are disposed at a distance apart and aligned transversely to a longitudinal extent of the conveyor belt and at ends of the supporting beams are disposed the mounted rollers.
  • the mounted rollers roll along the middle supporting cables and the lower supporting cables.
  • Supporting frames are disposed at a distance apart from each other in a longitudinal direction of the conveyor and by which the supporting cables are mutually connected.
  • Each of the supporting frames are formed from two at least approximately vertically aligned supporting struts and two at least approximately horizontally aligned connecting struts.
  • Upper ends of the vertically aligned supporting struts are respectively connected to one of the two upper supporting cables, and the horizontally aligned connecting struts are connected by clamping devices disposed thereon to the middle and to the lower supporting cables.
  • the clamping devices are disposed on the connecting struts and respectively assigned to the middle supporting cables.
  • the lower supporting cables form an acute angle with the connecting struts and the mounted rollers have a roller flange on one side only.
  • the clamping devices are hence subjected to far less bending load by lateral wind forces than is the case with the known conveyors. Furthermore, the fact that the rollers are configured with a roller flange on one side only avoids a situation in which one of the roller flanges runs up onto the clamping devices and, furthermore, the conveyor belt can be crossed over from a first track, for example supporting cables, to a second track, for example supporting rails, substantially more easily than is the case with the previously known conveyors in which the rollers are configured with roller flanges on both sides.
  • the clamping devices disposed on a respective connecting strut are inclined toward each other, and the rollers are configured with the roller flange on the side facing toward the conveyor belt.
  • the clamping devices are inclined away from each other, and the rollers are configured with the roller flange on the side facing away from the conveyor belt.
  • each clamping device has two clamping jaws, which at their ends facing away from the clamping surfaces are pivotable on the particular connecting strut about axes aligned at least approximately in the motional direction of the conveyor belt, the plane defined by the pivot axes of the two clamping jaws forming an acute angle of 5° to 60°, preferably of about 20°, with the connecting strut.
  • the plane of symmetry between the two clamping jaws forms an acute angle of 85° to 30°, preferably of about 70°, with the connecting strut.
  • the two clamping jaws can here be tied to the associated supporting cable by a tension bolt aligned parallel to the plane defined by their pivot axes.
  • the two clamping jaws form an acute angle of 5° to 50°, in particular of about 40°, with each other.
  • the clamping jaw facing toward the roller flange of the roller forms an acute angle of somewhat less than 90° with the connecting strut.
  • the outer surface of the rollers is configured with a running groove, as well as in the direction of the roller flange with at least one oblique surface and, on the side facing away from the roller flange, with a cylindrical running surface.
  • the rollers, away from the cable groove are configured with a first oblique surface, which forms an angle of 10° to 60°, preferably of about 35°, with the roller axis, and also with a second oblique surface, which forms an angle of 5° to 20°, preferably of about 10°, with the roller axis.
  • the clamping jaw facing toward the roller flange is preferably configured, on its side facing toward the roller flange, with a contact surface assigned to the roller flange.

  • FIG. 1 there is shown a portion of a conveyor for bulk materials, such as overburden materials, ores, coal and the like.
  • the conveyor consists of a self-contained conveyor belt 1 , which is moved between a loading station and an unloading station and which in the two end stations is guided over return drums.
  • An upper strand 11 of the conveyor belt 1 serves to convey the bulk materials from the loading station to the unloading station.
  • turning devices by which a lower strand 12 of the conveyor belt 1 , which strand has been moved from the unloading station back to the loading station, is turned such that, even when the lower strand 12 of the conveyor belt 1 has been moved back to the loading station, the loading surface is found on the top side thereof, whereupon the lower strand 12 is turned back again before the loading station and in this position is guided around the return drum present in the loading station.
  • the conveyor belt 1 is configured on its two side margins with lateral, elastically deformable bars, so-called corrugated sidewalls 13 , protruding up from its top side. Furthermore, the conveyor belt 1 is configured on its top side with supporting beams 14 which are aligned transversely to its motional direction and on the free ends of which are mounted rollers 2 .
  • the conveyor further has three pairs of supporting cables 31 to 36 , which are disposed one above the other and which are mutually connected by supporting frames 4 , whereby the entire conveyor is stabilized.

  • the lower supporting cables 35 and 36 the lower strand 12 of the conveyor belt 1 is moved in its turned position from the unloading station back to the loading station.
  • the approximately vertically upwardly directed corrugated sidewalls 13 are extensible, whereby the conveyor belt 1 can be guided in the stations over the return drums present there.
  • On the top side of the conveyor belt 1 are found the supporting beams 14 , at whose ends are mounted the rollers 2 , which roll along the supporting cables 33 to 36 .
  • the supporting frames 4 are formed by two vertical supporting struts 41 and 42 and by two horizontal connecting struts 43 and 44 .
  • the supporting struts 41 and 42 here respectively consist of two supporting strut parts 41 a and 41 b and 42 a and 42 b , which are articulately connected to each other by a hinge pin 41 c and 42 c respectively.
  • the two hinge pins 41 c and 42 c are aligned approximately horizontally and transversely to the supporting cables 31 to 36 .
  • the upper ends of the supporting strut parts 41 a and 42 a are mounted by hinge pins 41 d and 42 d , likewise pivotably about approximately horizontal axes aligned transversely to the supporting cables 31 to 36 , on supporting bars 45 and 46 , which are fixedly connected by brackets 45 a and 46 a to the upper supporting cables 31 and 32 .
  • the respectively upper supporting strut parts 41 a and 42 a are configured in their lower region with hubs 47 and 48 , into which the connecting strut 43 , configured as cylindrical pipe sections, projects and is rotatably mounted therein.
  • the lower supporting strut parts 41 b and 42 b are configured at their lower ends with hubs 49 and 50 , into which the lower connecting struts 44 , configured as cylindrical pipe sections, project and are rotatably mounted therein.
  • the connecting struts 43 and 44 are configured at their lateral ends with clamps 5 , by which they are fixedly connected to the middle supporting cables 33 and 34 and the lower supporting cables 35 and 36 .
  • the clamping devices 5 are located at the lateral ends of the connecting struts 43 and 44 of the holding frames 4 , wherein they form an acute angle of about 70° with the respective connecting strut 43 and 44 and wherein the two clamping devices 5 located on the connecting struts 43 and 44 are inclined toward each other.
  • the rollers 2 are configured with roller flanges 21 only on the side facing toward the strands 11 and 12 of the conveyor belt 1 .
  • the clamping devices 5 can be inclined in relation to the connecting struts 43 and 44 or in relation to the axes of the rollers 2 , without risk of the rollers 2 colliding with the clamping devices 5 .
  • the clamping devices 5 have two clamping jaws 51 and 52 , which are mounted pivotably about axes 51 a and 52 a on a supporting piece 53 provided on the connecting strut 43 and which can be tied by a screw bolt 54 , with intermediate compression spring 55 , to the respectively assigned supporting cable, in FIG. 3A the supporting cable 34 .
  • the clamping jaw 51 here forms an angle of somewhat less than 90° with the connecting strut 43
  • the clamping jaw 52 forms an angle of about 50° with the connecting strut 43
  • the two clamping jaws 51 and 52 form, for instance, an angle of 40° with each other
  • the plane of symmetry between the two clamping jaws 51 and 52 forms an angle of about 70° with the connecting strut 43 .
  • the rollers 2 are configured in their middle region with a running groove 22 , along which, in normal operation of the conveyor, they run along the associated supporting cables. Between the running groove 22 and the roller flange 21 is found an oblique surface 23 , which forms an angle of about 35° with the axis of the roller 2 .
  • the oblique surface 23 comes to bear against the supporting cable 34 when the strand 12 of the conveyor belt 1 , in particular due to wind forces, is laterally displaced.
  • the horizontal forces which are hereby exerted upon the clamping device 5 are here transmitted, in particular by the clamping jaw 52 , to the connecting strut 43 .

  • a cylindrical running surface 25 On the side facing away from the roller flange 21 is found on the roller 2 , next to the running groove 22 , a cylindrical running surface 25 , with which the roller 2 then runs on the cable run 34 as soon as the strand 12 of the conveyor belt 1 has been horizontally shifted in the opposite direction, whereupon the roller flange 21 of the roller 2 located on the other side comes to bear against the clamping device 5 located on the other side of the connecting strut 43 .
  • the axial length of the cylindrical running surface 25 is here somewhat greater than the distance of the side wall 21 a from the adjacent side edge of the running groove 22 .
  • FIG. 3B which corresponds to FIG. 3 , a second embodiment with respect to the tilt of the two clamping devices 5 and to the position of the roller flanges 21 is represented.
